Non-animal chitosan fibers and nonwovens for reducing menstrual stain visibility

Overview

Mykito Sciences offers non-animal chitosan fibers and nonwovens engineered to reduce menstrual stain visibility in feminine sanitary products. Unlike conventional absorbent materials, these chitosan-based structures selectively bind blood and retain moisture below the visible surface, keeping the top layer cleaner while preserving absorbency, comfort, and leak protection.

Chitosan's mechanism is well established in hemostatic wound care: protonated amino groups on the polymer electrostatically interact with negatively charged blood components, including erythrocyte membranes and plasma proteins. When incorporated into the absorbent core of a sanitary product, the material captures blood components and holds moisture beneath the surface, reducing visible staining. Because the chitosan is produced without animal sources, it offers a biocompatible, biodegradable option with bioburden-controlling properties and a lower regulatory burden for medical and hygiene applications.

Technical specifications

• Non-animal chitosan produced via proprietary fermentation technology, with high purity and low beta-glucan and heavy-metal content, under a GMP-compliant quality system in ISO 22000-certified facilities.
• Chitosan fibers and nonwovens manufactured at large scale; prototype feminine hygiene products available.
• Fiber morphology, pore structure, multilayer integration, and charge variant treatments can be engineered to tailor performance.
• Engineered charge gradients and multilayer structures support rapid fluid acquisition, directional transport from the visible surface into the absorbent core, selective blood binding, and moisture retention.
• Designed for integration into acquisition, distribution, or absorbent layers of existing feminine hygiene platforms.

Technology readiness level

The materials are at an advanced prototype stage. Representative non-animal chitosan fibers and nonwovens are available for technical evaluation and incorporation into existing hygiene platforms. Mykito Sciences works collaboratively to define performance requirements—including fluid acquisition rate, directional transport, absorbency, retention, compression performance, stain visibility, cost targets, and manufacturing compatibility—then develops and produces prototype material architectures. Prototypes are evaluated with blood or menstrual-fluid simulants under representative use conditions, with results used to refine fiber properties, layer configuration, and material placement. This iterative approach establishes a validated prototype architecture and informs a path toward scale-up and product integration.
